You are hired as a consultant to design the ventilation system for a 25,000 head tunnel ventilated broiler barn. Chicks enter the barn and broilers weighing 5 to 6 pounds exit the barn. Barn Dimensions: 42 ft wide by 475 ft long with 12ft ceilings. State assumptions used for the building construction. Assume no mechanical loads are on throughout the day, using LED lights. Calculate the following items for the chicks for a winter condition of 10 F, 50% RH with the inside conditions of 84F and 50 %RH.

a. Heat Balance

b. Moisture Balance

c. CO2 Balance

d. Determine your minimum ventilation rate for the barn.

e. Determine the maximum ventilation using tunnel airspeed method to achieve 350 fpm.
